RRB Junior Engineer / DMS / CMA 2019 · Question 3587 of 3719

Which of the following is NOT a characteristic of an SRS document?

  1. AVerifiability
  2. BCorrectness
  3. CModifiability
  4. DAmbiguityCorrect

Answer: D. Ambiguity

Explanation

Concept: Characteristics of SRS Document Correctness: User review is used to provide the accuracy of requirements stated in the SRS. SRS is said to be perfect if it covers all the needs that are truly expected from the system. Completeness: The SRS is complete if, and only if, all essential requirements, whether relating to functionality, performance, design, constraints, attributes, or external interfaces. Consistency: The SRS is consistent if, and only if, no subset of individual requirements described in its conflict Unambiguousness: SRS is unambiguous when every fixed requirement has only one interpretation. This suggests that each element is uniquely interpreted. In case there is a method used with multiple definitions, the requirements report should determine the implications in the SRS so that it is clear and simple to understand. Ranking for importance and stability: The SRS is ranked for importance and stability if each requirement in it has an identifier to indicate either the significance or stability of that particular requirement. Modifiability: SRS should be made as modifiable as likely and should be capable of quickly obtain changes to the system to some extent. Modifications should be perfectly indexed and cross-referenced. Verifiability: SRS is correct when the specified requirements can be verified with a cost-effective system to check whether the final software meets those requirements. The requirements are verified with the help of reviews. Traceability: The SRS is traceable if the origin of each of the requirements is clear and if it facilitates the referencing of each condition in future development or enhancement documentation. Hence Option 4 is correct
